● Use a picture with 0% gray value (black) and a suitable measuring instrument (a spot
meter is recommended) in order to reduce the brightness with the aid of the OSD control
elements until the measuring instrument displays constant values (i.e. the measured
value no longer changes). Then increase the brightness slightly until the display is just
above the lowest black level (one step is generally sufficient).
● The white value can be set in the same way. Again, use a test pattern with 100% gray
value (white) and the measuring instrument. Only the contrast should be adjusted, to
ensure that the black value remains unchanged.
● Increase the contrast until the measuring instrument no longer registers an increase in
light density. Then reduce the contrast to slightly below the maximum value (one or two
steps are usually sufficient).
● Make sure once again that the black value has not changed. If it should have changed,
repeat the two steps described above until the value no longer changes (cause: black
value reduction).
The display is now configured for optimum performance with the installed graphics card. If
you are still not satisfied with the light density, you can increase the black and white values
further by adjusting the backlighting in the OSD menu.
CAUTION
A permanently higher setting for the backlighting may reduce the brightness performance
Please note that a permanently higher setting for the backlighting results in a more rapid
reduction in the brightness performance toward the end of the service life.
